PoLoS: A Universal Platform for LBS and Data Services

This paper discusses the design and implementation of an integrated platform for location-based services (LBS) and other data services, including service creation, deployment, and provision. The PoLoS architecture includes components such as GPS, WLAN, UMTS, HTTP, GIS, and more. The platform offers portability, reusability, independence from underlying technologies, and support for various operation paradigms. The PoLoS consortium, comprised of 7 organizations across Europe, aims to provide a new platform for LBS deployment and provision.

  1. PoLoS: A Universal Platform for the Development of LBS and Other Data Services Platform for Location-Based Services Stathes Hadjiefthymiades, Lazaros Merakos Communication Networks Laboratory University of Athens IST Cluster Meeting for Engineering of Service Functionality Bucharest, Oct. 11, 2002

  2. Project Objectives • To design and implement an Integrated Platform for Location Based Services (LBS) for: • Service Creation • Service Deployment • Service Provision

  3. PoLoS Architecture Service Creation GPS MExE WLAN UMTS Text Data HTTP GIS Graph Data WAP GSM/GPRS PoLoS Kernel SMS Charging/Billing CORBA/IP Positioning Term Type OSA Network Infrastructure

  4. PoLoS Key Elements • PoLoS Kernel • Peripheral Components: • G.I.S. • Positioning • Interfaces (SMS/MMS, WAP, HTTP, IP) • LBS Specification Language • Service Creation Environment • Generic LBS Provider Business Model • Contributions to Standardisation & Clustering

  5. Main Advantages of PoLoS (1/2) • Portability: platform independent of specific hardware/operating systems • Re-usability: generic platform, decoupled from service logic - basic components unaffected by dynamic new service introduction • Independence from underlying technologies: • platform not bound to specific network technologies. Covers both outdoor and indoor environments (GSM/GPRS, UMTS and WLAN) • platform not coupled with specific GIS • Open interfaces towards the GIS, the network and end-user devices • Support for many operation paradigms(e.g., server push, client pull, event scheduling)

  6. Main Advantages of PoLoS (2/2) • Flexible Service Handling • Service Creation Environment handles the XML-based service specification • service logic fully covered by the platform. Service specified through the SCE, deployed & executed in the kernel • Roaming across different infrastructures (e.g., moving from an outdoor/GPS to an indoor/WLAN environment) • Generic system infrastructure tied with generic business model • separation between service creation, service provisioning and the network, allowing each function to be handled by independent (yetcooperating) organisations.

  7. The Consortium Project Officer: Dr. Franco Accordino • ALCATEL SEL AG • CSEM • University of Athens • INTRACOM S.A. • EPSILON S.A. • Telefonica I+D • EPSILON Consulting Ltd.

  8. PoLoS Consortium Composition • Highly focused project involving 7 organisations, from 5 European countries, with complementary know-how: • Two major telecom manufacturers with expertise on systems engineering and standardisation • Two R&D institutions with expertise on mobile networks and services • Two R&D partners specialised in G.I.S. • A mobile network operator

  9. Target Audience • Providers of innovative telecommunications services (LBS in particular) • Telecom operators wishing to extend the range of their VAS by exploiting positioning capabilities offered by their infrastructure • Large organizations wishing to exploit LBS platforms internally (e.g., fleet-management) • Other Organizations: Universities, R&D centers or industries wishing to exploit LBS technologies in their premises

  10. Exploitable Results • A new platform: allows the deployment and provision of LBS over different network infrastructures • A Service Creation Environment / Specification Language: easy service creation and deployment • A prototype service:deployment and provisioning using the developed platform • A generic process model: allows service providers to fully realise the potential of the developed platform

  11. Definition of a Business Model • An architecture for: • Product • Service • Information flows • Business Actors and their Roles • potential benefits for the various Business Actors • sources of revenue

  12. PoLoS Business Models • An important aspect of the PoLoS project is theintroduction/proposal of a business model specially designed, tailored to organisations that exclusively provide Location Based Services to various sectors of economic activity. Such models will be structured appropriately to optimally exploit the outcome of PoLoS. PoLoS Generic LBS Platform Generic Business Model

  13. Service Specification Language • The specification language consists of the following parts: • Service control logic • Configuration options • Embedded components • Web Server pages • WAP pages • Custom java classes/libraries • Midlets • These parts are defined in a single XML file, which completely specifies the service.

  14. Service Creation, Deployment & Provision Service & Platform Management Service Creation Text Editor Deployment Provision PoLoS Kernel Visual Editor

  15. Potential Collaboration Areas • Service Creation (textual/visual service representation, service design, interfaces, Service Control Language) • Service Provision platform design • Platform/Service Management • Billing/Charging Support • Component Design (Interfaces, Positioning) • Definition/standardisation of open interfaces • Business Models • Indoor LBS

  16. Current Project Status • Project started on Mar 2002. • Platform Design/Specification finished by Aug 2002. • Trial Scenarios defined. • Three deliverables released so far (one major technical deliverable). • Implementation work started by Sep 2002. • Member of the Lobster cluster since May 2002.
